Ensure i_plasma_pedestal=0 profile does not have 0 elements

[timothy-nunn]

Adds in a check of the profile_y when i_plasma_pedestal=0 to set any 0 elements to be slightly above 0, hence avoiding divide by 0's.

Just to clarify this is what the profile looks like

Obviously, that was the case before except the final point is now at 1e-8 not 0.0

Did this remove the error for you @timothy-nunn ?

[ym1906]

This is actually being overwritten by the following code, so the fix isn't applied and the error persists. We should add a return statement after this, then an else or "if physics.variables.i_plasma_pedestal == 1" to ensure the code runs correctly.

Please make the adjustment recommended in profiles.py

One more thing @timothy-nunn the change is only applied to the ne profile but actually the bug occurs with the te profile, we should apply the same solution there.
